Coprophanaeus acrisius (MacLeay) (recomb. by Blackwelder 1944: 209 [as synonym of C. jasius ])

Type. P. acrisius – neotype male (des. by Arnaud, 2002b: 3), The Natural History Museum, London (examined) ; P. camargoi – holotype male, Museu de Zoologia, Universidade de São Paulo, São Paulo .

Diagnosis. General – Posterior portion of head and pronotum bright metallic green or yellowish green; elytral interstriae dull bronze, striae and margins of elytra bright green. Clypeal margin rounded ( Fig. 119, 122 ), not noticeably angulate or explanate lateral to median teeth. Pronotum (as in Fig. 97 ) with elongate triangular depression densely packed with coarse granules, extending from posterior margin to middle of disk; area adjacent to depression and extending along posterior pronotal margin somewhat swollen, densely and rather coarsely punctatorugose to granulorugose. Basal pronotal fossae distinct. Elytral striae at most only very weakly carinulate ( Fig. 100 ). Length 22-30 mm.

Male ( Fig. 121-123 ) – Base of head horn flat. Anteromedian pronotal concavity shallow, bordered posteriorly by distinctly tridentate transverse carina.

Female ( Fig. 119-120 ) – Cephalic carina straight, median tubercle larger than laterals. Pronotal ridge elevated, trapezoidal, tridentate.

Specimens examined – 35.

Comments. Coprophanaeus acrisius is the northern partner of the C. spitzi – C. acrisius species pair. MacLeay proposed C. acrisius as variety of C. jasius , and we cite its original name above, in accordance with ICZN Article 45.6.4 ( ICZN 1999), as Phanaeus jasius acrisius MacLeay. Fernando Vaz-de-Mello (pers. comm.) has also observed specimens from the coast of Maranhão.
